Description

La présente invention a pour objet un vernis-à-ongles comprenant une dispersion aqueuse de polymère filmogène et un agent épaississant. Ce vernis peut être employé pour le maquillage des ongles ou bien encore pour le traitement des ongles.The subject of the present invention is a nail varnish comprising a dispersion aqueous film-forming polymer and a thickening agent. This varnish can be used for nail makeup or even for nail treatment.

Il est connu des demandes EP-A-143480, FR-A-2399238, et EP-A-648485 des compositions de vernis-à-ongles fluides comprenant une dispersion aqueuse de particules de polymère filmogène.EP-A-143480, FR-A-2399238, and EP-A-648485 are known from fluid nail polish compositions comprising an aqueous dispersion of film-forming polymer particles.

Dans les vernis à ongles à milieu aqueux, il est courant d'épaissir la phase aqueuse par des agents épaississants. Ces compositions épaissies permettent de faciliter la prise du produit hors de son conditionnement sans perte significative, de répartir le produit de façon régulière sur la zone à traiter ou bien encore de pouvoir utiliser le produit dans des quantités suffisantes pour obtenir l'effet cosmétique recherché.In aqueous nail polishes, it is common to thicken the phase aqueous with thickening agents. These thickened compositions allow facilitate taking the product out of its packaging without significant loss, distribute the product evenly over the area to be treated or even ability to use product in sufficient quantities to achieve cosmetic effect research.

Toutefois, ces compositions étant fluides, il est souvent nécessaire d'appliquer deux couches de produit pour obtenir un film couvrant parfaitement l'ongle, c'est-à dire un film qui ne permette pas de voir l'ongle à travers le film. Il est donc souhaitable de disposer de vernis-à-ongles présentant une bonne propriété de couvrance.However, these compositions being fluid, it is often necessary to apply two layers of product to obtain a film covering the nail perfectly, i.e. say a film that does not allow to see the nail through the film. It is therefore desirable to have nail polish with good coverage.

Par ailleurs, un vernis-à-ongles doit présenter également les qualités suivantes : facilité d'étalement du vernis sur l'ongle et obtention d'un film brillant, homogène, présentant de bonnes propriétés de maquillage, notamment d'aspect lisse.In addition, a nail polish must also have the following qualities: ease of spreading the varnish on the nail and obtaining a shiny, homogeneous film, having good makeup properties, in particular of smooth appearance.

Le but de la présente invention est de disposer d'une composition de vernis-à-ongles comprenant une dispersion aqueuse de particules de polymère filmogène s'étalant facilement sur l'ongle et conduisant, après application en une seule couche sur l'ongle, à un film parfaitement brillant, homogène, couvrant l'ongle et lisse.The aim of the present invention is to have a nail polish composition comprising an aqueous dispersion of film-forming polymer particles spreads easily on the nail and conducts, after application in a single layer on the nail, with a perfectly shiny, homogeneous film, covering the nail and smooth.

La demanderesse a découvert qu'une telle composition pouvait être obtenue en ajustant la viscosité et en employant un agent épaississant particulier.The Applicant has discovered that such a composition can be obtained by adjusting the viscosity and using a specific thickening agent.

Ainsi, l'invention a pour objet une composition de vernis-à-ongles comprenant une dispersion aqueuse de particules de polymère filmogène, caractérisée par le fait que la composition comprend au moins un polyuréthane associatif en une quantité efficace pour que la composition ait une viscosité d'au moins 2 Pa.s, mesurée à 23°C, à la vitesse de rotation de 100 tours/min.Thus, the subject of the invention is a composition of nail polish comprising a aqueous dispersion of film-forming polymer particles, characterized in that that the composition comprises at least one associative polyurethane in an amount effective so that the composition has a viscosity of at least 2 Pa.s, measured at 23 ° C, at a rotation speed of 100 rpm.

L'invention a aussi pour objet l'utilisation d'un polyuréthane associatif dans un vernis-à-ongles comprenant une dispersion aqueuse de particules de polymère filmogène et ayant une viscosité d'au moins 2 Pa.s, mesurée à 23°C, à la vitesse de rotation de 100 tours/min.The invention also relates to the use of an associative polyurethane in a nail polish comprising an aqueous dispersion of polymer particles film-forming and having a viscosity of at least 2 Pa.s, measured at 23 ° C, at the speed rotation of 100 revolutions / min.

L'invention a encore pour objet l'utilisation d'un polyuréthane associatif dans une composition de vernis-à-ongles comprenant une dispersion aqueuse de particules de polymère filmogène, en une quantité efficace pour que la composition ait une viscosité d'au moins 2 Pa.s, mesurée à 23°C, à la vitesse de rotation de 100 tours/min.Another subject of the invention is the use of an associative polyurethane in a nail polish composition comprising an aqueous dispersion of particles of film-forming polymer, in an amount effective for the composition to have a viscosity of at least 2 Pa.s, measured at 23 ° C, at a speed of rotation of 100 revolutions / min.

L'invention a également pour objet l'utilisation d'une composition telle que définie précédemment pour l'obtention d'un film brillant et/ou homogène et/ou couvrant.The subject of the invention is also the use of a composition as defined previously to obtain a glossy and / or homogeneous and / or covering film.

L'invention a encore pour objet l'utilisation d'une composition telle que définie précédemment comme vernis monocouche.Another subject of the invention is the use of a composition as defined above as a monolayer varnish.

L'invention a aussi pour objet l'utilisation d'une composition telle que définie précédemment comme vernis pelliculable.The invention also relates to the use of a composition as defined above as a film-based varnish.

L'invention a pour objet un procédé de maquillage ou de traitement cosmétique et non thérapeutique des ongles consistant à appliquer sur les ongles une composition telle que définie précédemment.The subject of the invention is a make-up or cosmetic treatment process and non-therapeutic nails consisting in applying to the nails a composition as defined above.

Les inventeurs ont constaté que les polyuréthanes associatifs permettent d'obtenir les propriétés remarquables de vernis-à-ongles et que d'autres agents épaississants connus dans les vernis à consistance fluide ne permettaient pas d'obtenir ces propriétés rhéologiques ou cosmétiques souhaitées. Par exemple, les argiles comme la bentonite ou la montmorillonite ne conduisent pas à des viscosités supérieures à 2 Pa.s ; les polymères cellulosiques comme l'hydroxyéthylcellulose conduisent à la matification du film pour les viscosités recherchées ; les polymères épaississants de type acrylique, y compris les polymères acryliques associatifs, ne permettent pas un étalement satisfaisant pour les viscosités souhaitées.The inventors have found that associative polyurethanes make it possible to obtain the remarkable properties of nail polish and other thickening agents known in fluid consistency varnishes did not allow obtaining these desired rheological or cosmetic properties. For example, clays like bentonite or montmorillonite do not lead to higher viscosities at 2 Pa.s; cellulosic polymers such as hydroxyethylcellulose lead to the matification of the film for the desired viscosities; polymers acrylic thickeners, including associative acrylic polymers, do not not allow satisfactory spreading for the desired viscosities.

Grâce au polyuréthane associatif et à la viscosité élevée de la composition, on obtient un vernis-à-ongle qui s'étale facilement sur l'ongle et qui permet d'obtenir, par application en une seule couche, un film présentant une bonne couvrance. De plus, le film est parfaitement homogène et lisse, sans traces de pinceau. Le film obtenu après séchage présente aussi une bonne brillance : la brillance, mesurée à l'aide d'un brillancemètre BYK-GARDNER à un angle de faisceau lumineux de 60 °, est supérieure ou égale à 80, et notamment va de 80 à 100.
Le vernis selon l'invention permet le dépôt d'un film épais sur l'ongle tout en étant appliqué en une seule couche. Aussi, le vernis selon l'invention est parfaitement utilisable comme vernis pelliculable. Thanks to the associative polyurethane and the high viscosity of the composition, a nail polish is obtained which spreads easily on the nail and which makes it possible to obtain, by application in a single layer, a film having good coverage. . In addition, the film is perfectly homogeneous and smooth, with no brush marks. The film obtained after drying also has good gloss: the gloss, measured using a BYK-GARDNER glossmeter at a light beam angle of 60 °, is greater than or equal to 80, and in particular ranges from 80 to 100 .
The varnish according to the invention allows the deposition of a thick film on the nail while being applied in a single layer. Also, the varnish according to the invention is perfectly usable as a coating varnish.

La viscosité de la composition selon l'invention est d'au moins 2 Pa.s (2000 cps) et de préférence inférieure à 8 Pa.s car au delà, la composition n'est plus applicable à l'aide d'un pinceau. Avantageusement, la viscosité de la composition peut aller de 4 Pa.s (4000 cps) à 6 Pa.s (6000 cps).
La viscosité est mesurée à 23 °C, avec un viscosimètre BROOKFIELD DVII équipé du mobile n°3, à une vitesse de rotation de 100 tours/min, la mesure étant effectuée après 10 minutes de rotation (temps au bout duquel on observe une stabilisation de la viscosité et de la vitesse de rotation du mobile).The viscosity of the composition according to the invention is at least 2 Pa.s (2000 cps) and preferably less than 8 Pa.s because beyond, the composition is no longer applicable using a brush . Advantageously, the viscosity of the composition can range from 4 Pa.s (4000 cps) to 6 Pa.s (6000 cps).

Les polyuréthannes associatifs sont des copolymères séquencés non ioniques comportant dans la chaíne, à la fois des séquences hydrophiles de nature le plus souvent polyoxyéthylénée et des séquences hydrophobes qui peuvent être des enchaínements aliphatiques seuls et/ou des enchaínements cycloaliphatiques et/ou aromatiques.Associative polyurethanes are nonionic block copolymers comprising in the chain, both hydrophilic sequences of the most often polyoxyethylenated and hydrophobic sequences which can be Aliphatic sequences alone and / or cycloaliphatic sequences and / or aromatic.

En particulier, ces polymères comportent au moins deux chaínes lipophiles hydrocarbonées, ayant de C6 à C30 atomes de carbone, séparées par une séquence hydrophile, les chaínes hydrocarbonées peuvent être des chaínes pendantes ou des chaínes en bout de séquence hydrophile. En particulier, il est possible qu'une ou plusieurs chaínes pendantes soient prévues. En outre, le polymère peut comporter, une chaíne hydrocarbonée à un bout ou aux deux bouts d'une séquence hydrophile.In particular, these polymers comprise at least two lipophilic hydrocarbon chains, having from C 6 to C 30 carbon atoms, separated by a hydrophilic block, the hydrocarbon chains can be pendant chains or chains at the end of hydrophilic block. In particular, it is possible that one or more hanging chains are provided. In addition, the polymer may comprise a hydrocarbon chain at one end or at both ends of a hydrophilic block.

Les polymères peuvent être séquencés sous forme de tribloc ou multibloc. Les séquences hydrophobes peuvent donc être à chaque extrémité de la chaíne (par exemple : copolymère tribloc à séquence centrale hydrophile) ou réparties à la fois aux extrémités et dans la chaíne (copolymère multiséquencé par exemple). Les polymères peuvent être également en greffons ou en étoile.The polymers can be sequenced as a triblock or multiblock. The hydrophobic sequences can therefore be at each end of the chain (for example: triblock copolymer with hydrophilic central block) or distributed at the same time at the ends and in the chain (multi-block copolymer for example). The polymers can also be in grafts or in star.

De préférence, les polymères sont des copolymères triblocs dont la séquence hydrophile est une chaíne polyoxyéthylénée comportant de 50 à 1 000 groupements oxyéthylénés. En général les polyuréthannes associatifs comportent une liaison uréthane entre les séquences hydrophiles, d'où l'origine du nom.Preferably, the polymers are triblock copolymers whose hydrophilic block is a polyoxyethylenated chain comprising from 50 to 1000 groups oxyethylenated. In general, associative polyurethanes have a bond urethane between hydrophilic sequences, hence the origin of the name.

Par extension figurent aussi parmi les polyuréthannes associatifs, des polymères dont les séquence hydrophiles sont liées par d'autres liaisons chimiques que la liaison uréthane aux séquences lipophiles.By extension also appear among associative polyurethanes, polymers whose hydrophilic sequences are linked by other chemical bonds than urethane bond to lipophilic sequences.

    On a ensuite préparé 6 vernis-à-ongles ayant les compositions données dans le tableau ci-après (base + épaississant) puis on a étudié les qualités de maquillage de ces vernis déposés en une couche: on a mesuré la brillance du film obtenu après séchage et on a évalué l'aspect du film et du maquillage. We then prepared 6 nail polishes having the compositions given in the table below (base + thickener) then we studied the makeup qualities of these varnishes deposited in a layer: the gloss of the film obtained was measured after drying and the appearance of the film and make-up was evaluated.

    On a obtenu les résultats suivants : Exemple 3 4 5 6 7 (HI) 8 (HI) Base 96,1 g 92,9 g 97,3 g 97,2 g 96,1 g 96,6 g Epaississant 0,8 g E1 2 g E2 0,6 g E3 0,7 g E4 0,5 g E5 0,4 g E6 Viscosité (Pa.s) 4,01 3,76 4,43 4,54 3,68 3,73 Brillance 89 87 87 88 74 14 Aspect du film Lisse Lisse Lisse Lisse Pas très lisse Inhomogène Maquillage de l'ongle Correct Correct Correct Correct Trace de pinceau Inhomogène HI : hors invention Agents épaississants : la teneur est donnée en matière active E1 : Borchigel LW 44 de BORCHERS E2 : Serad 1070 de SERVO HÜLS E3 : Rhéolate 205 de RHEOX E4 : Serad FX 1100 de SERVO HÜLS E5 : Copolymère acrylique Acrysol 33 de ROHM & HAAS E6 : Copolymère acrylique Thixol 53L de COATEX The following results were obtained: Example 3 4 5 6 7 (HI) 8 (HI) Based 96.1 g 92.9g 97.3 g 97.2 g 96.1 g 96.6 g Thickening 0.8 g E1 2 g E2 0.6 g E3 0.7 g E4 0.5 g E5 0.4 g E6 Viscosity (Pa.s) 4.01 3.76 4.43 4.54 3.68 3.73 Shine 89 87 87 88 74 14 Aspect of the film Smooth Smooth Smooth Smooth Not very smooth Inhomogeneous Nail makeup Correct Correct Correct Correct Brush trace Inhomogeneous HI: outside invention Thickening agents: the content is given in active material E1: Borchigel LW 44 from BORCHERS E2: SERO 1070 from SERVO HÜLS E3: RHEOX Rheolate 205 E4: Serad FX 1100 from SERVO HÜLS E5: Acrysol 33 acrylic copolymer from ROHM & HAAS E6: Thixol 53L acrylic copolymer from COATEX

    La brillance a été mesurée pour un film humide déposé de 300 µm d'épaisseur déposé sur carte de contraste puis conservé pendant 24 h, dans une atmosphère à 50 % d'humidité relative, pendant 24 h. La mesure a été effectuée à l'aide d'un brillancemètre BYK-GARDNER avec un angle de faisceau lumineux de 60°.The gloss was measured for a wet film deposited 300 μm thick deposited on a contrast card and then stored for 24 hours, in an atmosphere at 50% relative humidity, for 24 h. The measurement was made using a BYK-GARDNER glossmeter with a light beam angle of 60 °.

    On a ainsi constaté que seules les compositions 3 à 6 selon l'invention permettent d'obtenir un film brillant, lisse et ne présentant pas de trace de pinceau.
    La composition 7 (hors invention) conduit à la formation d'un film moins brillant, pas très lisse, laissant apparaítre des traces de pinceau.
    La composition 8 (hors invention) conduit à la formation d'un film inhomogène et le maquillage n'est pas satisfaisant.    It has thus been found that only compositions 3 to 6 according to the invention make it possible to obtain a film which is shiny, smooth and which does not have any brush marks.
    Composition 7 (outside the invention) leads to the formation of a less shiny film, not very smooth, revealing traces of the brush.
    Composition 8 (outside the invention) leads to the formation of an inhomogeneous film and the make-up is not satisfactory.
